Parent: Cattleya x hardyana
Mentioned in Orchid Rev. 3: 322 in 1895.
We have received from Mr. W. J. Robertson, The Gardens, Ardenholm, Maghull, Cheshire, a very beautiful form of Cattleya X Hardyana with white sepals and petals. The lip is very similar to the typical form in colour, and the contrast is very striking. It may be called C. X Hardyana alba.
